cm-1 were quantitatively utilized to determine the amounts of p-and m-cresol, respectively, while bands at 830 and 900 cm-1 were used for p-and m-chlorophenols, respectively. Multiple isomer distribution determinations were done on six cresol mixtures, giving good, reproducible results.C. For Chlorinated Products.-Aryl chloride yields were performed along with phenol yields by glpc (columns A and B). Columns A and C were used to determine the isomeric compositions of the chlorinated hydrocarbons.D. For HC1.-The general procedure was followed except that the reaction flask was continuously purged with nitrogen which was then bubbled through an aqueous sodium hydroxide trap. Titration of aliquots from the trap before and after the reaction gave the amount of acid formed. The yield of HC1
